  1. Verified Buyer (verified owner) –

    This is the second complete upper I’ve purchased in addition to numerous parts for other builds. I compared this one to an Aero m16a4 upper and it’s part-for-part a match on quality and workmanship – and it was half the price. If anyone asks me where to get parts I send them a link to BKF.

  2. unforgivinsouly (verified owner) –

    Very well gassed. Paired up with a pri lower/bcg. No issues with lc and south african 55gr ball.

    Wanted to have a m16 inspired build in the safe. Ticks all the boxes

  3. Brinton Evans (verified owner) –

    Ordered 6 days ago, received the upper today. I ordered the rail and BCG and it came assembled, test fired, and ready to go. Impressed. As a former 45B, and Ordnance School instructor, I am beyond happy. Wrapped up nicely, inspection sheet, the brass in a bag, signed off assembler and inspector, the stickers, just all of it was what I hoped to get from other places.

    I took it out, zeroed irons, and then the ACOG. no issues. Handloads 55gr and 75gr got me moa-1.5moa. I’m rusty, but so far it’s showing promise.

    I will be coming back here from now on. I’m done trying elsewhere. Clearly this Marine owner has his operations dress right dress and it shows. Even the rail is super nice, T marked and all. Just a yes from tip to butt.

  4. Hunter Reed (verified owner) –

    Very happy with the quality of this upper and for the price you cant beat it

  5. Seth (verified owner) –

    Functions good so far, good deal to get into full 20” performance
